Assigns the specified size to the arrow contained in an arrow object with the specified ID number; . Arw_SetSize returns a value of 0 if the size was successfully assigned, and a value of -2 if the specified object ID number is invalid.

==== Usage ====<syntaxhighlight>Arw_SetSize(ObjectID,ArrowSize)</syntaxhighlight>

Where: ObjectID - a numerical expression specifying the object ID number

:'''ObjectID''' - a numerical expression specifying the object ID number. :'''ArrowSize ''' - a numerical expression specifying the arrow size .

==== Notes ==== * An object-specific ID number is returned assigned by [[Arw_New]], [[Arw_New_s]], [[Arw_New_self]] or [[Arw_New_self_s]] when the arrow object is created.* Use [[Arw_GetActive]], [[Arw_GetFirst]] or [[Arw_GetNext]] to get the object-specific ID number of an already created arrow.

==== Example ====

<syntaxhighlight>Value1=Arw_SetSize(3,10);</syntaxhighlight>
